Hello, Does anyone know about some measurements in terms of performance for cross joins compared to joins inside a single index?
Is it faster the join inside a single index that stores all documents of various types (from parent table or from children tables)with a discriminator field compared to the cross join (basically in this case each document type resides in its own index)? I have performed some tests but to me it seems that having a join in a single index (bigger index) does not add too much speed improvements compared to cross joins. Why a block join would be faster than a cross join if this is the case? What are the variables that count when trying to improve the query execution time? Thanks! Mihaela
